Objective To analyze the influencing factors of plastic bronchitis in children with Mycoplasma pneumoniae infection and put forward targeted prevention suggestions. Methods The clinical data of children with Mycoplasma pneumoniae infection who were admitted to Chengdu Third People's Hospital from September 2022 to February 2024 were retrospectively analyzed . According to whether plastic bronchitis occurred, they were divided into plastic group (n=118) and non-plastic group (n=184), and the differences between the two groups were compared and analyzed. Univariate and multivariate logistics regression analysis equations were used to analyze the independent influencing factors of plastic bronchitis in children with mycoplasma pneumoniae infection. Results Among the 302 children with Mycoplasma pneumoniae infection , 118 cases were diagnosed with plastic bronchitis. Analysis showed that the children’s age, duration of fever, hospital stay, pleural effusion rate, number of bronchoscopic lavage, allergy history, endoscopic mucosal erosion rate, WBC, NE%, LY%, CRP, LDH, PCT and D-D were the single factors influencing the occurrence of plastic bronchitis in children with mycoplasma pneumoniae infection. Binary logistics regression analysis revealed that age (OR=2.137, P=0.033, 95% CI: 1.132-16.603), allergy history （OR=3.028, P=0.014, 95% CI: 1.261-864), NE% (OR=2.395, P=0.031, 95% CI: 1.087-5.274), CRP (OR=3.864, P=0.004, 95% CI: 1.563-3.864), PCT (OR=4.125, P=0.001, 95% CI: 1.793-3.864), and D-D (OR=3.920, P=0.002, 95% CI: 1.632-3.864) were independent risk factors for plastic bronchitis in children with mycoplasma pneumoniae infection (P<0.05). Conclusion Age, allergy history, NE%, CRP, PCT and D-D are independent risk factors for plastic bronchitis in children with mycoplasma pneumoniae infection . It is necessary to take clinical intervention measures to reduce the occurrence risk.

Objective: To determine the clinical efficacy of platelet-rich plasma (PRP) injection combined with warm acupuncture and moxibustion for treating patients with knee osteoarthritis and cold dampness obstruction syndrome. Methods: One hundred and twenty-eight patients with knee osteoarthritis and cold dampness obstruction syndrome who visited the Rehabilitation Department and Orthopedics Department of the Second Affiliated Hospital of Anhui University of Chinese Medicine from January 2023 to March 2024 and who met the inclusion and exclusion criteria were randomly divided into an experimental (n=64) and control group (n=64) using the random number table method. The experimental group was treated with PRP injection combined with warm acupuncture and moxibustion, whereas the control group was treated with normal saline injection combined with warm acupuncture and moxibustion treatment. PRP and normal saline injections were administered once every two weeks, a total of four times. Patients were treated with warm acupuncture and moxibustion once a day, six times a week, for four consecutive weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Traditional Chinese Medicine (TCM) syndrome, visual analog scale (VAS), and Lysholm scores were determined before treatment, at week 4 and week 8 of treatment, and week 16 of follow-up. Serum interleukin-6 (IL-6), matrix metalloproteinase-3 (MMP-3), tumor necrosis factor-α (TNF-α), osteoprotegerin (OPG), bone gla protein(BGP), and cartilage oligomeric matrix protein (COMP) levels were compared between the two groups before and after 8 weeks of treatment. The clinical efficacy and safety indicators between the two groups were also compared. Results: There was no statistical difference in baseline data such as gender, age, disease duration, and body mass index between the two groups of patients. Compared with before treatment, both groups showed decreased WOMAC total and subscale, TCM syndrome total score and symptom scores, and VAS scores, and an increase in Lysholm scores at 4, 8, and 16 weeks after treatment. After treatment, serum IL-6, MMP-3, TNF-α, and COMP levels decreased, whereas serum OPG and BGP levels increased (P<0.05). Compared with the control group, patients in the experimental group showed decreased WOMAC total and subscale, TCM syndrome total score and symptom scores, and VAS scores, and an increase in Lysholm score at 4, 8, and 16 weeks after treatment. Compared with the control group, patients in the experimental group showed decreased serum IL-6, MMP-3, TNF-α, and COMP levels and an increase in serum OPG and BPG levels after treatment (P<0.05). The total effective rate of the experimental group was 91.94%, higher than that of the control group (81.97%; P<0.05). Conclusion PRP injection combined with warm acupuncture and moxibustion can improve various TCM symptoms, improve knee joint function and bone metabolism, and reduce inflammation in patients with knee osteoarthritis and cold dampness obstruction syndrome.

ObjectiveTo observe the effects of modified Chaihu Shugansan on the calmodulin-dependent protein kinase Ⅱ（CaMKⅡ）/cAMP-response element binding protein （CREB） signaling pathway in the hippocampus and heart tissue of a rat model with myocardial ischemia and depression and explore the mechanism by which this formula prevents and treats coronary heart disease combined with depression. MethodsThe model of myocardial ischemia combined with depression was established by high-fat diet， intraperitoneal injection of isoproterenol （ISO）， and chronic unpredictable mild stress （CUMS）. A total of 108 SD male rats were randomly divided into normal group， model group， high （23.4 g·kg^-1）， medium （11.7 g·kg^-1）， and low （5.85 g·kg^-1） dose groups of modified Chaihu Shugansan， CaMKⅡ inhibitor （KN93） group， and KN93 + high， medium， and low dose groups of modified Chaihu Shugansan， with 12 rats in each group. From the first day of modeling to the end of modeling， drugs were administered once a day. In the seventh and eighth weeks， the KN93 group and the KN93 + high， medium， and low dose groups of modified Chaihu Shugansan were intraperitoneally injected with KN93 three times weekly. At the end of the eighth week， behavioral tests including sucrose preference， open field， and elevated plus maze were conducted. Electrocardiogram （ECG） lead Ⅱ changes were observed in each group of rats， and hematoxylin-eosin （HE） staining was performed to observe changes in heart tissue. Serum levels of triglycerides （TG）， total cholesterol （TC）， high-density lipoprotein （HDL）， low-density lipoprotein （LDL）， and lactate dehydrogenase （LDH） were measured by using an enzyme-labeled instrument. Creatine kinase （CK） and creatine kinase-MB （CK-MB） were detected by ultraviolet spectrophotometry， while serum monocyte chemoattractant protein-1 （MCP-1） was measured by enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA expression of CaMKⅡ and CREB in hippocampal and heart tissue， and Western blot was performed to assess protein expression of CaMKⅡ， phosphorylated （p）-CaMKⅡ， CREB， and p-CREB. ResultsCompared to the normal group， the model group showed significant reductions in sucrose preference rate， total activity distance in the open field， number of entries into the center area of the open field， and percentage of entries into the open arms of the elevated plus maze （P<0.01）. The ECG showed ST-segment elevation， and HE staining showed serious degeneration of myocardial fibers， disordered arrangement， and infiltration of a large number of inflammatory cells. In addition， serum TC and LDL levels increased （P<0.01）， and HDL level decreased （P<0.01）. CK， CK-MB， LDH， and MCP-1 levels significantly increased （P<0.05， P<0.01）. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB decreased in the hippocampal tissue （P<0.05， P<0.01）， but those increased in the heart tissue （P<0.01）. Compared to the model group， the high， medium， and low dose groups of modified Chaihu Shugansan showed improvements in these abnormalities. The KN93 group had reduced sucrose preference， total activity distance in the open field， number of entries into the center area of the open field， and percentage of entries into the open arms of the elevated plus maze （P<0.01）， as well as decreased serum CK， CK-MB， LDH， and MCP-1 levels （P<0.05， P<0.01）. KN93 also reduced ST-segment elevation， alleviated the degeneration degree of myocardial fibrosis， and lowered inflammatory cell infiltration. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB in both the hippocampal and heart tissue were reduced （P<0.05， P<0.01）. The KN93 + high， medium， and low dose groups of modified Chaihu Shugansan showed further improvements in these abnormalities compared to the KN93 group. ConclusionThe modified Chaihu Shugansan exerts antidepressant and myocardial protective effects in rats with myocardial ischemia and depression， possibly related to bidirectional regulation of the CaMKⅡ/CREB signaling pathway， with the high-dose modified Chaihu Shugansan showing the best effects.

Objective:To study the effects of applying the think-pair-share (TPS) method combined with the microlecture teaching model in nursing teaching of general surgery.Methods:We assigned 48 nursing students interning in the department of general surgery of The First Affiliated Hospital of Air Force Medical University from August 2020 to August 2021 into control group to receive traditional teaching and 48 nursing students who interned from September 2021 to August 2022 into observation group to receive TPS+microlecture teaching. The two groups were compared in terms of test results, critical thinking abilities, post competencies, and satisfaction with teaching. SPSS 22.0 was used to perform the t test and chi-square test. Results:The observation group showed a significantly higher theoretical score [(93.21±4.34) vs. (88.65±3.69)], a significantly higher basic nursing skills score [(94.21±3.85) vs. (89.45±5.47)], and a significantly higher specialized skills score [(90.76±4.59) vs. (88.96±3.63)] than the control group ( P<0.05). The total score of the critical thinking ability scale and the scores of individual dimensions were significantly increased after training for both groups, and all the scores were significantly higher in the observation group than in the control group ( P<0.05). Both groups had significant improvements in the total and individual scores of post competencies after training, and the observation group had significantly higher scores than the control group ( P<0.05). Compared with the control group, the observation group had significantly higher proportions of students feeling satisfied with teaching, in terms of all evaluation items and also overall ( P<0.05). Conclusions:Applying the TPS+microlecture teaching model in general surgery nursing teaching can help nursing students improve theoretical and practical levels, critical thinking abilities, and post competencies, also with a high level of satisfaction with teaching.

Background::Influenza and pneumococcal vaccination are a priority in patients with chronic obstructive pulmonary disease (COPD). However, limited information is available on vaccination coverage among patients with acute exacerbations of COPD (AECOPD) in China. This study aimed to determine the rates and associated factors of influenza and pneumococcal vaccination in patients hospitalized with AECOPD.Methods::Baseline data from a national, multicenter, hospital-based study that included adult inpatients with AECOPD between 2017 and 2021 were analyzed. The outcomes of interest were the influenza vaccination in the past year and the pneumococcal vaccination in the past 5 years. To ensure national representativeness, rates were weighted according to the distribution of hospital levels and types enrolled in this study. Multivariable Poisson regression based on mixed-effects models were used to determine the associated factors. The independent variables included the region and hospital features where the participants were located, sociodemographic characteristics (age, sex, rural/urban residence, education, etc.), and clinical indicators (COPD disease history, lung function parameters, comorbidities, etc.). The treatment profiles of the vaccinated and unvaccinated participants were compared.Results::Of 6949 eligible participants, the weighted rates of influenza/pneumococcal, influenza, and pneumococcal vaccination were 2.72% (95% confidence interval [CI]: 2.34%-3.10%), 2.09% (95% CI: 1.76%-2.43%), and 1.25% (95% CI: 0.99%-1.51%), respectively. In multivariable models, age ≥60 years (60-69 years, odds ratio [OR]: 1.90, 95% CI: 1.11-3.25; ≥80 years, OR: 2.00, 95% CI: 1.06-3.78), geographical regions (Northern China relative to Eastern China, OR: 5.09, 95% CI: 1.96-13.21), urban residence (OR: 1.69, 95% CI: 1.07-2.66), a higher education level (junior high school, OR: 1.77, 95% CI: 1.21-2.58; senior high school or above, OR: 2.61, 95% CI: 1.69-4.03), former smoking (OR: 1.79, 95% CI: 1.15-2.79), and regular inhaled medication treatment (OR: 3.28, 95% CI: 2.29-4.70) were positively associated with vaccination. Patients who had experienced severe exacerbations in the past year were less likely to be vaccinated (OR: 0.65, 95% CI: 0.45-0.96). Compared with unvaccinated participants, vaccinated participants adhered better to pharmacological and non-pharmacological treatment.Conclusions::Influenza and pneumococcal vaccination coverage are extremely low. Urgent measures are necessary to increase vaccination coverage among inpatients with AECOPD in China.

Objective:To investigate the effect of programmed blood glucose management model on blood glucose control and prognosis in patients with sepsis and diabetes mellitus.Methods:Seventy-six patients with sepsis and diabetes mellitus who received treatment at the Fifth Hospital Affiliated to Wenzhou Medical University (Lishui Central Hospital) were included in this study. According to the implementation time of programmed blood glucose management model, the patients were divided into a routine group ( n = 37; receiving routine nursing between January 2021 and December 2022) and an experimental group ( n = 39, receiving routine nursing and programmed blood glucose management). Length of hospital stay, 28-day mortality rate, blood glucose control level (glycosylated hemoglobin level, blood glucose variability, incidence of hypoglycemia, fasting blood glucose level, and 2-hour postprandial glucose level), and health status (Medical Outcomes Study-36-Item Shot-Form Health Status Survey) as well as incidence of adverse events were compared between the two groups. Results:The length of hospital stay in the experimental group was (14.85 ± 2.77) days, which was significantly shorter than that in the routine group [(17.42 ± 3.24) days, t = 3.72, P < 0.001]. The 28-day mortality rate in the experimental group was 7.69% (3/39), which was significantly lower than that in the control group [24.32% (9/37), χ2 = 3.95, P = 0.047]. The level of glycated hemoglobin and blood glucose variability in the experimental group were 10.4 (8.5, 12.1) mmol/L and (31.54 ± 7.16)%, which were significantly lower than those in the routine group [12.8 (8.9, 15.3) mmol/L, (45.63 ± 12.19)%, Z = 6.88, P < 0.001; t = 6.18, P < 0.001]. There was no significant difference in the incidence of hypoglycemia between the experimental and routine groups [10.81% (4/37) vs. 5.13% (2/39), χ2 = 0.84, P = 0.358]. After the intervention, the experimental group had higher scores in various dimensions of the 36-Item Shot-Form Health Status Survey, including limitations [(72.21 ± 5.37) points], bodily pain [(82.98 ± 6.41) points], general health [(81.32 ± 6.23) points], and physical function [(71.43 ± 5.22) points] compared with the routine group [(68.39 ± 6.21) points, (78.35 ± 6.17) points, (74.50 ± 7.57) points, (65.57 ± 6.96) points, t = 2.87, P = 0.005; t = 3.20, P = 0.002; t = 4.29, P < 0.001; t = 4.16, P < 0.001]. There was no significant difference in the incidence of adverse events between the experimental and routine groups [10.26% (4/39) vs. 13.51% (5/37), χ2 = 0.19, P = 0.660]. Conclusion:Programmed blood glucose management model can improve blood glucose control level and prognosis of patients with sepsis and diabetes mellitus.

Objective:To investigate the clinical characteristics in older adult patients with sepsis and heart failure, and to analyze the influential factors of prognosis.Methods:Eighty-eight older adult patients with sepsis and heart failure who received treatment at Lishui Central Hospital from January 2020 to December 2022 were retrospectively included in the heart failure group. Eighty-eight older adult patients with sepsis, who did not have heart failure, were selected in a 1:1 ratio to form a non-heart failure group. Based on their survival status during hospitalization, the patients in the heart failure group were divided into two subgroups: the survival group and the death group. Logistic regression analysis was performed to identify the risk factors associated with the development of heart failure and adverse disease outcomes in older adult patients with sepsis.Results:There were no statistically significant differences in sex, smoking history, alcohol consumption history, history of hypertension, and history of diabetes between the heart failure group and the non-heart failure group (all P > 0.05). However, the proportion of patients aged 75 years or older in the heart failure group was 52.27% (46/88), which was significantly higher than the proportion in the non-heart failure group [34.09% (30/88), χ2 = 5.93, P < 0.05]. The proportion of patients with respiratory system infections in the heart failure group was 53.41% (47/88), which was significantly higher than the proportion in the non-heart failure group [29.55% (26/88), χ2 = 10.37, P < 0.05]. Logistic regression analysis showed that advanced age and respiratory system infections are independent risk factors for the development of heart failure in patients with sepsis. Among patients with sepsis and heart failure, 45 survived and 43 died, resulting in a mortality rate of 48.86%. The average age of patients in the death group was (76.27 ± 4.14) years, which was significantly higher than that in the survival group [(72.29 ± 4.06) years, t = 4.55, P < 0.05]. The brain natriuretic peptide level and the Acute Physiology and Chronic Health Evaluation II (APACHE II) score in the death group were (636.70 ± 70.29) pg/mL and (31.93 ± 3.08) points, respectively, both of which were significantly higher than those in the survival group [(552.80 ± 54.66) pg/mL, (27.06 ± 3.80) points, t = 6.27, 6.59, both P < 0.05]. The lactate clearance rate and serum albumin level in the death group were (13.63 ± 4.84)% and (26.09 ± 4.77) g/L, respectively, both of which were significantly lower than those in the survival group [(19.94 ± 5.07)%, (30.55 ± 5.17) g/L, t = 5.97, 4.20, both P < 0.05]. Logistic regression analysis showed that in patients with sepsis and heart failure, advanced age, elevated serum brain natriuretic peptide levels, and high APACHE II scores are risk factors for poor prognosis and death. A high lactate clearance rate at 24 hours and elevated serum albumin levels are protective factors for survival. Conclusion:Advanced age and respiratory system infections increase the risk of heart failure in patients with sepsis. Advanced age, elevated brain natriuretic peptide levels, and high APACHE II scores are associated with an increased risk of death in these patients. High lactate clearance rates and elevated serum albumin levels are indicative of a reduced risk of death in patients with sepsis.

Objective To investigate the effect of subanesthetic dose of esketamine for postoperative analgesia on early recovery in elderly patients undergoing laparoscopic radical resection of rectal cancer.Methods Elderly patients undergoing laparoscopic radical resection of rectal cancer were included,and they were divided into the AS group(61 cases received esketamine for intravenous self-controlled analgesia)and the SF group(60 cases received sufentanil for intravenous self-controlled analgesia)by random number table method.The operation time,intraoperative infusion volume,urine output,intraoperative blood loss,postoperative rescue analgesia,tramadol dosage and the number of patient controlled intravenous analgesia(PCIA)compressions within 48 hours after surgery,postoperative visual analogue scale(VAS)score,Ramsay sedation score,first ambulation time after surgery,first gas passage time after surgery,and first feeding time after surgery were compared between the two groups.The occurrence of adverse reactions in the two groups was recorded.The levels of interleukin-6(IL-6)and C-reactive protein(CRP)immediately after surgery,24 hours and 72 hours after surgery in the two groups were detected by ELISA.The scores of anxiety and depression 3 days,1 week and 1 month after surgery were compared between the two groups.Results There was no significant difference in the operation time,intraoperative infusion volume,urine output,intraoperative blood loss,postoperative rescue analgesia,tramadol dosage or PCIA compressions within 48 hours after surgery between the two groups(P＞0.05).The levels of IL-6 and CRP gradually increased immediately after surgery and 24 hours and 72 hours after surgery in the two groups(P＜0.05),and the levels of IL-6 and CRP 24 hours and 72 hours after surgery in the AS group were significantly lower than those in the SF group(P＜0.05).The first ambulation time after surgery,first gas passage time after surgery,and first feeding time after surgery in the AS group were earlier than those in the SF group(P＜0.05).The incidences of nausea,vomiting and dizziness in the AS group were significantly lower than those in the SF group(P＜0.05).The levels of IL-6 and CRP 24 hours and 72 hours after surgery in the AS group were significantly lower than those in the SF group(P＜0.05).The scores of anxiety and depression 3 days and 1 week after surgery in the AS group were significantly lower than those in the SF group(P＜0.05).Conclusion Subanesthetic dose of esketamine for postoperative analgesia can alleviate short-term postoperative anxiety and depression in elderly patients undergoing laparoscopic radical resection of rectal cancer,relieve postoperative pain and inflammatory responses and have a low incidence of adverse reactions,which contribute to early recovery of patients.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To explore the effect of comprehensive moxibustion with Huolong cupping in patients with lung-spleen qi deficiency type allergic rhinitis.Methods:This study was a randomized controlled trial. From October 2022 to April 2023, convenience sampling was used to select 66 patients with lung-spleen qi deficiency type allergic rhinitis who visited the Otolaryngology Head and Neck Clinic of Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine as the research subject. The patients were randomly divided into an experimental group ( n=33) and a control group ( n=33). Both groups received routine oral Chinese medicine treatment. On the basis of routine treatment, the experimental group performed comprehensive moxibustion with Huolong cupping on the meridians of the Du meridian and bladder meridian. This study compared the scores of Nasal Airway Resistance (NAR), Total Nasal Symptom Score (TNSS), Visual Analogue Scale (VAS), and Chinese version of Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) between two groups of patients before and after intervention. Results:Eventually 30 patients in each of the experimental group and control group completed the study. After intervention, the NAR score of the experimental group was lower than that of the control group, and the difference was statistically significant ( P<0.05). Repeated measures analysis of variance showed that with the increase of treatment time, the TNSS, VAS, and RQLQ scores of the experimental group were lower than those of the control group with statistical differences ( P<0.05), and the time effect, inter group effect, and interaction effect were statistically significant ( P<0.05) . Conclusions:Huolong cupping comprehensive moxibustion can reduce nasal resistance, meliorate nasal symptoms and accompanying nasal symptoms, and improve the quality of life of patients.
